中文摘要: 个体在社会经济网络中相互作用机制直接影响了社会经济系统的稳定性与绩效产出。本项目基于在线虚拟社会中海量游戏用户的经济活动和社交行为数据,提取蕴含于网络结构属性和社会属性中的个体行为偏好,探索社会经济网络的演化机理与动力学规律,基于个体的多属性(结构属性与社会属性)与多机制(流行性、相似性、嗜异性)构建社会经济网络中个体连边形成的决策模型。通过对模型的校验和分析,从个体决策层面揭示社会经济系统演化的内在机理,并据此设计和构建社会经济网络演化的计算实验平台,分析个体决策机制影响社会网络稳定性和绩效产出的关键因素。本项目的研究成果可推广到现实社会,不仅可以深化人们对社会经济网络演化机理的科学认识,还可以为预测和控制社会经济网络健康、稳定发展提供可靠有效的思想与方法。

英文摘要: The evolutional mechanisms of socioeconomic networks have important effects on the stability and performance of socioeconomic systems. This study is conducted on a huge database from Virtual Worlds (socioeconomic systems), which records all the detail information of social and economical activities for each individual in that system. By uncovering the individual preferences on different characters (social positions and attributes) in the socioeconomic networks, we proposed a multiple mechanism (including popularity, similarity, homogeneity and heterophily) model to capture the individual strategies for attaching links based on multiple preferences on different social attributes. By calibrating the model with empirical results, we will carry out computational experiments to uncover the impact of different mechanisms on the stability and performance of the social networks. Our research will provide new theories and methods for the management of socioeconomic organizations and shed light on promoting stability and performance of socioeconomic systems.
